Define Natural Resources. (Notes: Non-renewable Energy Sources)

Define Non-renewable Energy.

• Non-renewable Energy are natural resources that are being USED UP FASTER THAN THEY ARE REPLACED by natural processes.

• Non-renewable Energy are resources that can be replaced quickly by natural processes.

• Non-renewable Energy are resources that never run out.

• Non-renewable Energy are resources that are always available in unlimited amounts.

List the 2 types of Non-renewable Energy.

• 1. Fossil Fuels 2. Minerals

• 1. Solar Energy 2. Wind Energy

• 1. Biomass 2. Geothermal

• 1. Hydropower 2. Tidal Energy

What are Fossil Fuels? List 3 examples.

• Fossil fuels are resources formed from decayed remains of organisms that died millions of years ago. Examples include coal, oil and natural gas.

• Fossil fuels are minerals found only in volcanic rocks. Examples include gold, silver and copper.

• Fossil fuels are renewable resources formed from living plants. Examples include wood, wind and solar energy.

• Fossil fuels are synthetic chemicals made in laboratories. Examples include plastic, nylon and polyester.

Describe advantages of Fossil Fuels.

• Fossil fuels provide a lot of energy for us. Cost-effective power plants, with pipeline transport, have been built to use fossil fuels.

• Fossil fuels are renewable and never run out.

• Fossil fuels do not cause any pollution.

• Fossil fuels are the only source of energy available.

Describe disadvantages of Fossil Fuels.

• Fossil fuels are formed underground and must be drilled or mined, which disrupts the environment. Fossil fuels take millions of years to form naturally, so we can run out. Fossil fuels can cause pollution on land, air and water. The pollutants can harm organisms and cause acid precipitation which can also damage infrastructure.

• Fossil fuels are easily renewable and do not cause any pollution. They are formed quickly and are found on the surface.

• Fossil fuels are only used for making jewelry and have no impact on the environment.

• Fossil fuels are made from plants that grow every year and do not require mining or drilling.

How is Nuclear Energy produced? What mineral is commonly used for Nuclear Energy?

• Nuclear Energy is released when the nuclei of atoms are split in a process called NUCLEAR FISSION. Uranium is the most common mineral to use for Nuclear Energy.

• Nuclear Energy is produced by burning fossil fuels. Coal is the most common mineral to use for Nuclear Energy.

• Nuclear Energy is released when water is boiled to produce steam. Iron is the most common mineral to use for Nuclear Energy.

• Nuclear Energy is produced by combining hydrogen and oxygen. Gold is the most common mineral to use for Nuclear Energy.

Describe advantages of Nuclear Energy.

• Nuclear Energy provides large amounts of energy. Nuclear Energy releases low amounts of carbon-dioxide pollutants.

• Nuclear Energy is a renewable source of energy. Nuclear Energy is available everywhere.

• Nuclear Energy produces no waste at all. Nuclear Energy is completely risk-free.

• Nuclear Energy is generated by burning fossil fuels. Nuclear Energy increases air pollution.

Describe disadvantages of Nuclear Energy.

Define Renewable Energy and list examples

• Renewable Energy are natural resources that CAN BE NATURALLY REPLENISHED at least as QUICKLY as they are used, like wind, solar, water/hydropower, geothermal and biomass energy.

• Renewable Energy are resources that can only be used once, such as coal, oil, and natural gas.

• Renewable Energy refers to energy sources that are always man-made, like nuclear and synthetic fuels.

• Renewable Energy are resources that deplete quickly and cannot be replaced, such as fossil fuels.
